AUTOMATIC RAIL-LUBRICATOR.

Specification of Letters Patent.

Patented July 29, 1919.

Application filed February 19, 1919. Ber1a1No.277,960.

To all 'whom it may concern.

Be it known that I, ERNEST Tnnononn FRANZEN, a, subject of King Gustavus V of Sweden, and a resident of 58 Glenmore Boulevard, Jamaica South, in. the county of Queens and State of New York, have invented certain new and useful Improvements in Automatic Rail-Lubricators, of which the following is a specification.

This invention relates to rail lubricators, and especially to that class of lubricators which is carried as a permanent fixture beneath a car and derives the necessary pressure for applying the lubricant from an air tank.

It is the object of this invention to lubricate the innerface of the outside rails on railroad curves by employing,r the changed relative positions of the car truck and the body as an automatic means of opening the lubricant valves and causingr the lubricant to' be applied through suitable means herein described.

Referring' to the drawings, like numerals refer to the same parts throughout the views.

Figure 1 is a plan vievfof a model car truck equipped with an apparatus embodyingr the presentinvention, with a portion of tank 27 and valve parts 7 and 8 in section to expose the interior. Fig. 2 is a side view of Fig. 1. Fig. 3 is a plan View of a modification of the invention` with only essential parts shown. Fig. 4 is an enlarged front view of grease shoe 1 and its related parts as illustrated in Figs. l and Fig. 5 is a 4considerably enlarged side View of the same grease shoe 1 with a section of its supporting bur 10. Fig. (i is a view of the oil brush that sets into recess 37 of Fig. 5.

It is well known that upon yrailroads generally there is a tremendous wear and tear mutually inflicted upon the outer rails of curves on the said. roads and the` wheel Hang-es of the rolling stock. This has become doubly true in the last twcnty years because of the increase in the wciifht of rolling stock und the great speed of modern traffic.

It is with the end in view of practically `eliminatingy this troublesome problem and its attendant expense that the present invention hasbeen. designed.

A lubricant tank 27 is secured to a car body as partially indicated by dotted lines at 23 and likewise brackets 244 und 25, and isv air brake system on the car. Un either side of the tank are situated valves 7 and 15, both of which have their pistons connected to and actuated by a rockingr cam plate 9 which is provided. with a pair of corresponding slots on either side, the stud of piston 8 engaging slot S. The plate 9 is centered at 3 upon the forward end of tank 27 and contains further a long slot 9. The truck 19 has extendingr from its crossbeam 6 a cam rod 11 whose stud engages andv is adapted to slidevin slot 9 of plate 9. The position of the truck as shown onthe straight rails 20 and 21 leave the entire apparatus inactive. Howeveimthc forward journals 18 and 22 support pendant grease applicators adapted to slide against the inner faces of rails 20 and 21. The mounting of one of these grease shoes 1 is made more clear in Figsyand 5, the pivot 29 permittingr shoe 1 toswingi-slightly as the shape of the cross bar',which supports the two applicators limits the swing of the grease applicator or shoe, an added spring 30 insuring contact between the shoe angl the rail. The valves 7 and 15 are connected to the grease shoes on their respective sides by flexible tubes 4 and 5, perinittingthe truck 19 to turn Without any obstruction.

If the truck 19 were to be run up on a curved track as indicated at 16 and 17, the cam bar l1 would change its position to that indicated at 12, and would draw the cam plate 9 into a position indicated at 13 bccause of the form of slot .9. This would draw piston 8 into open position in valve 7, and as there is considerable air pressure in theehamber to the right of blind piston,

2 in tank 27, the grease in the chamber to the left would be forced out through tube 4 to shoe 1 and from the same applied alongr the inner, face of the outside rail 16 until a straight track is again reached. Ther-inside rail 17 receives no grease, and it is thus seen that the apparatus is entirely automatic in operation.

When the grease is exhausted from ta-nk 27, valve 14 is closed, and petcock 26 opened. This releases the air in the tank.v The plug 28 is then removed and a grease gun or container connected to the aperture' and grease forced into the tank under pressure. Then plug 28 is replaced, peteock 26 closed and valve 14 o y cned, Iand t apparatus is again in order. Figs.`5- an 6 Will beseen more furnished rcalwvardly with petcock 26 and particular the details of grease applicator air valve 1&1 which connects directly to thc l. The nipple l1 is the anchorage for the grease tubing 4, the grease passing down through indicated channel 36 and out through aperture 1. However, in order to properly spread the grease, a ring brush 38 is secured in the recess 37 by friction or other means, the bristles ol the brush engaging the rail directly, the nose of the shoe being really only a guide and protection for the brush. The latter is, of course, easily renewable when worn out.

In Fig. 3 another form of my invention appears.y The cam bar 11 has here been replaced by a bar 33 which bears a roller 32 in. contact with a cam plate 31. The tank Q7 is only indicated and likewise its valves by dotted lines. If the'cross beam 6 were to turn clockwise upon its axis the cam bar 31 would assume a position indicated at 40 and the cam plate would rock into a position seen at 39. This would push valve rod 34 into open position While it would pull rod 35 in the opposite direction. It is clearly evident that this operation though opposite to the operation of the other form described is identical in result and is really exactly the same in principle.

Likewise, a single valve alone being o erated by a rocking cani plate would be i entical with my invention, and doubling this or having two valves and an individual plate for each While employing the same cam bar would still be the same principle.

vHaving thus fully described my invention, I desire to obtain by United States 'Letters Patent. .y

1. A rail lubricator including a lubricant container, a valve upon one portion thereof,A

a piston extending from said valve, a rocker cani plate centered upon a portion of said container and provided with a portion adapted to cngave the piston rod of said valve, and a cam bar adapted to engage portions of said cam plate to move the same and open said valve by moving said piston, said cam bar and said container being respectively secured to a truck and the body of -a railway car.

2. A rail lubrieator including a car with truck an extension provided with a swing ,l grease applicator and limits u on said eX-f',

tension ormedby the Sides o said eXtension or bar in the proximity of the pivot of the grease applicator to limit the radius of action of said applicator, and a nose upon the forward ortion of said a plicator.

4. A rail ubricator inclu ing upon the truck of a car an extension bearing a rock ing member held thereby in contact with the inner face of the rail adjacent thereto, and a spring secured u on said extension and tensed against said rocking member to insure contact between the latter and the rail.

5. A rail lubricator including a rail wiping member mounted upon a car truck and adapted to lie against a side face of a rail beneath said car, and a ring brush situated in a recess in said member and slu'roundin sail grease outlet and contacting with sai rai 6. A grease applicator for railways including an elongated pendant body plvoted at one end and provided at the other end with a forwardly extendin pointed portion and upon the side of said att/er end with a grease vent. y y
